Super easy processes and I'm loving it so far. Was running just long tubes catless for a little bit. Without the tune I felt downlow rpm was a little funky and I had the CEL on. Just felt like the car was a little upset. It's nice to see a clean dash again and now the car feels way more smooth through the rev range. Throttle response also feels a bit better as well. When I got the intake from JLT they made sure to emphasize that their intake its not just a bolt on. I have to get a tune for it
